perf tools: Make rm_rf() remove single file (2019-02-20 17:09:28 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf report:
He Kuang:
- Don't shadow inlined symbol with different addr range.
perf script:
Jiri Olsa:
- Allow +- operator to ask for -F to add/remove fields to
the default set, for instance to ask for the removal of the
'cpu' field in tracepoint events, adding 'period' to that
kind of events, etc.
perf test:
Thomas Richter:
- Fix scheduler tracepoint signedness of COMM fields failure of
'evsel-tp-sched' test on s390 and other arches.
Tommi Rantala:
- Skip trace+probe_vfs_getname.sh when 'perf trace' is not built.
perf trace:
Arnaldo Carvalho de Melo:
- Add initial BPF map dumper, initially just for the current, minimal
needs of the augmented_raw_syscalls BPF example used to collect
pointer args payloads that uses BPF maps for pid and syscall filtering,
but will in time have features similar to 'perf stat' --interval-print,
--interval-clear, ways to signal from a BPF event that a specific
map (or range of that map) should be printed, optionally as a
histogram, etc.
General:
Jiri Olsa:
- Add cpu and numa topologies classes for further reuse, fixing some
issues in the process.
- Fixup some warnings and debug levels.
- Make rm_rf() remove single file, not just directories.
Documentation:
Jonas Rabenstein:
- Fix HEADER_CMDLINE description in perf.data documentation.
- Fix documentation of the Flags section in perf.data.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

# perf trace -h
perf: 'trace' is not a perf-command. See 'perf --help'

Check trace support, so that we'll skip the test in that case:

From: Jiri Olsa <jolsa@kernel.org>
Make struct cpu_topo global and rename it to 'struct cpu_topology', so
that it can be used from the 'perf record' command in the following
patches.
Add the following interface functions to load/free cpu topology details:
struct cpu_topology *cpu_topology__new(void);
void cpu_topology__delete(struct cpu_topology *tp);
Move it to a separate source file cputopo.c together with numa related
object in the following patches.
No functional change, the new interface will be used in upcoming changes.

From: Jiri Olsa <jolsa@kernel.org>
Add the numa_topology object to return the list of numa nodes together
with their cpus. It will replace the numa code in header.c and will be
used from 'perf record' in the following patches.
Add the following interface functions to load numa details:
struct numa_topology *numa_topology__new(void);
void numa_topology__delete(struct numa_topology *tp);
And replace the current (copied) local interface, with no functional
changes.

Use sysfs__mountpoint() when reading sysfs files to obtain cpu/numa
topologies.
Also use scnprintf instead of sprintf as suggested by Namhyung.

From: He Kuang <hekuang@huawei.com>
We can't assume inlined symbols with the same name are equal, because
their address range may be different. This will cause the symbols with
different addresses be shadowed when adding to the hist entry, and lead
to ERANGE error when checking the symbol address during sample parse,
the addr should be within the range of [sym.start, sym.end].
The error message is like: "0x36aea60 [0x8]: failed to process type: 68".
The second parameter of symbol__new() is the length of the fake symbol
for the inline frame, which is the subtraction of the end and start
address of base_sym.

assumption.

Commit 489338a717a0 ("perf tests evsel-tp-sched: Fix bitwise operator")
causes test case 14 "Parse sched tracepoints fields" to fail on s390.
This test succeeds on x86.
In fact this test now fails on all architectures with type char treated
as type unsigned char.
The root cause is the signed-ness of character arrays in the tracepoints
sched_switch for structure members prev_comm and next_comm.
On s390 the output of:
[root@m35lp76 perf]# cat /sys/kernel/debug/tracing/events/sched/sched_switch/format
name: sched_switch
ID: 287
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
...
field:char prev_comm[16]; offset:8; size:16; signed:0;
...
field:char next_comm[16]; offset:40; size:16; signed:0;
reveals the character arrays prev_comm and next_comm are per
default unsigned char and have values in the range of 0..255.
On x86 both fields are signed as this output shows:
[root@f29]# cat /sys/kernel/debug/tracing/events/sched/sched_switch/format
name: sched_switch
ID: 287
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
...
field:char prev_comm[16]; offset:8; size:16; signed:1;
...
field:char next_comm[16]; offset:40; size:16; signed:1;
and the character arrays prev_comm and next_comm are per default signed
char and have values in the range of -1..127. The implementation of
type char is architecture specific.
Since the character arrays in both tracepoints sched_switch and
sched_wakeup should contain ascii characters, simply omit the check for
signedness in the test case.
Output before:
[root@m35lp76 perf]# ./perf test -F 14
14: Parse sched tracepoints fields :
--- start ---
sched:sched_switch: "prev_comm" signedness(0) is wrong, should be 1
sched:sched_switch: "next_comm" signedness(0) is wrong, should be 1
sched:sched_wakeup: "comm" signedness(0) is wrong, should be 1
---- end ----
14: Parse sched tracepoints fields : FAILED!
[root@m35lp76 perf]#
Output after:
[root@m35lp76 perf]# ./perf test -Fv 14
14: Parse sched tracepoints fields :

---- end ----

From: Arnaldo Carvalho de Melo <acme@redhat.com>
At some point I'll suggest moving this to libbpf, for now I'll
experiment with ways to dump BPF maps set by events in 'perf trace',
starting with a very basic dumper for the current very limited needs
of the augmented_raw_syscalls code: dumping booleans.
Having functions that apply to the map keys and values and do table
lookup in things like syscall id to string tables should come next.

Initial use case:
Dumping the maps setup by tools/perf/examples/bpf/augmented_raw_syscalls.c,
which so far are just booleans, showing just non-zeroed entries:
# cat ~/.perfconfig
[llvm]
dump-obj = true
clang-opt = -g

#add_events = /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o

Next step probably will be something like 'perf stat's --interval-print and
--interval-clear.

There's no reason to deliver a sample with zero period. It means there
was no value for slave event since its last group leader sample.

Force sample_type setup for slave events in group leader sessions.
We don't get sample for slave events, we make them when delivering group
leader sample. Set the slave event to follow the master sample_type to
ease up report.

Add support to add/remove fields for specific event types in -F option.
It's now possible to use '+-' after event type, like:
# cat > test.c
#include <stdio.h>
int main(void)
{
printf("Hello world\n");
while(1) {}
}
^D
# gcc -g -o test test.c
# perf probe -x test 'test.c:5'
# perf record -e '{cpu/cpu-cycles,period=10000/,probe_test:main}:S' ./test
...
# perf script -Ftrace:+period,-cpu
test 3859 396291.117343: 10275 cpu/cpu-cycles,period=10000/: 7f..
test 3859 396291.118234: 11041 cpu/cpu-cycles,period=10000/: ffffff..
test 3859 396291.118234: 1 probe_test:main:
test 3859 396291.118248: 8668 cpu/cpu-cycles,period=10000/: ffffff..
test 3859 396291.118263: 10139 cpu/cpu-cycles,period=10000/: ffffff..
Committer testing:
Couldn't make the test above work, but tested it with:
# perf probe -x hello main
Added new event:
probe_hello:main (on main in /home/acme/c/hello)
You can now use it in all perf tools, such as:
perf record -e probe_hello:main -aR sleep 1
# perf record -e probe_hello:main ./hello
hello, world
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.025 MB perf.data (1 samples) ]
# perf script
hello 21454 [002] 254116.874005: probe_hello:main: (401126)
#
# perf script -Ftrace:+period,-cpu

Add a missing new line into pr_debug call in perf_event__synthesize_bpf_events(),
so that the error message does not screw the verbose output.

Test results at the end of this message, as usual.
The following changes since commit 1159e09476536250c2a0173d4298d15114df7a89:
perf/x86/intel: Enable C-state residency events for Cannon Lake (2018-03-31 11:28:36 +0200)

perf trace: Remove redundant ')' (2018-04-03 16:16:41 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Show only failing syscalls with 'perf trace --failure' (Arnaldo Carvalho de Melo)
e.g: See what 'openat' syscalls are failing:
# perf trace --failure -e openat
762.323 ( 0.007 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video2) = -1 ENOENT No such file or directory
<SNIP N /dev/videoN open attempts... sigh, where is that improvised camera lid?!? 8-) >
790.228 ( 0.008 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video63) = -1 ENOENT No such file or directory
^C#
- Show information about the event (freq, nr_samples, total period/nr_events) in
the annotate --tui and --stdio2 'perf annotate' output, similar to the
first line in the 'perf report --tui', but just for the samples for
the annotated symbol (Arnaldo Carvalho de Melo)
- Introduce 'perf version --build-options' to show what features were
linked, aliased as well as a shorter 'perf -vv' (Jin Yao)
- Add a "dso_size" sort order (Kim Phillips)
- Remove redundant ')' in the tracepoint output in 'perf trace' (Changbin Du)
- Synchronize x86's cpufeatures.h, no effect on tools (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (9):
tools headers: Synchronize x86's cpufeatures.h
perf trace: Show only failing syscalls
perf hists browser: Rename perf_evsel_browser_title to a more descriptive name
perf hists: Introduce hists__scnprint_title()

perf ui browser: Move the extra title lines from the hists browser
perf annotate: Introduce annotation__scnprintf_samples_period() method
perf annotate browser: Show extra title line with event information
perf annotate stdio2: Print more descriptive event information header
Changbin Du (1):

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support. Where clang is available, it is also used to build
perf with/without libelf.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

perf tests bpf: Use SyS_epoll_wait alias (2016-08-03 19:40:48 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
- Add --sample-cpu to 'perf record', to explicitely ask for sampling
the CPU (Jiri Olsa)
Fixes:
- Fix processing of multi byte chunks in objdump output, fixing
disassemble processing for annotation on at least ARM64 (Jan Stancek)
- Use SyS_epoll_wait in a BPF 'perf test' entry instead of sys_epoll_wait, that
is not present in the DWARF info in vmlinux files (Arnaldo Carvalho de Melo)
- Add -wno-shadow when processing files using perl headers, fixing
the build on Fedora Rawhide and Arch Linux (Namhyung Kim)
Infrastructure:
- Annotate prep work to better catch and report errors related to
using objdump to disassemble DSOs (Arnaldo Carvalho de Melo)
- Add 'alloc', 'scnprintf' and 'and' methods for bitmap processing (Jiri Olsa)
- Add nested output resorting callback in hists processing (Jiri Olsa)

Hi Ingo,
Please consider pulling,
- Arnaldo
The following changes since commit 1b6de5917172967acd8db4d222df4225d23a8a60:
perf/x86/intel/pt: Convert ACCESS_ONCE()s (2016-05-05 10:16:29 +0200)
are available in the git repository at:

perf evlist: Rename variable in perf_mmap__read() (2016-05-05 21:04:04 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Order output of 'perf trace --summary' better, now the threads will
appear ascending order of number of events, and then, for each, in
descending order of syscalls by the time spent in the syscalls, so
that the last page produced can be the one about the most interesting
thread straced, suggested by Milian Wolff (Arnaldo Carvalho de Melo)
- Do not show the runtime_ms for a thread when not collecting it, that
is done so far only with 'perf trace --sched' (Arnaldo Carvalho de Melo)
- Fix kallsyms perf test on ppc64le (Naveen N. Rao)
Infrastructure:
- Move global variables related to presence of some keys in the sort order to a
per hist struct, to allow code like the hists browser to work with multiple
hists with different lists of columns (Jiri Olsa)
- Add support for generating bpf prologue in powerpc (Naveen N. Rao)
- Fix kprobe and kretprobe handling with kallsyms on ppc64le (Naveen N. Rao)
- evlist mmap changes, prep work for supporting reading backwards (Wang Nan)
